Vedclass · Answer

(B) Predators play a crucial role in maintaining ecological balance. They act as conduits for energy transfer across trophic levels. Furthermore,they help maintain species diversity in a community by reducing the intensity of competition among competing prey species. For example,in the rocky intertidal communities of the American Pacific Coast,the starfish $Pisaster$ is an important predator. In a field experiment,when all the starfish were removed from an enclosed intertidal area,more than $10$ species of invertebrates became extinct within a year,species of invertebrates became extinct because of interspecific competition.
